Abstract

Устройство (24а) для обнаружения протечки в канале (16) трубопровода включает в себя кожух (26), сообщающийся посредством текучей среды с каналом (16), клапан (56), включающий в себя седло (64) клапана, и вентильный элемент (62) с возможностью перемещения относительно седла (64) между открытым и закрытым положениями, обводной канал (58) вокруг клапана (56), датчик (60) расхода, соединенный с обводным каналом (58) для обнаружения проходящего через него потока текучей среды, а также механизм (88), выполненный с возможностью приведения вентильного элемента (62) в закрытое положение и удержания вентильного элемента (62) в закрытом положении, пока не будет достигнуто пороговое падение давления на вентильном элементе. Механизм может работать на принципе магнетизма.A device (24a) for detecting leakage in a duct (16) of a pipeline includes a casing (26) in fluid communication with a channel (16), a valve (56) including a valve seat (64), and a valve element (62 ) can be moved relative to the seat (64) between the open and closed positions, the bypass channel (58) around the valve (56), the flow sensor (60) connected to the bypass channel (58) to detect the fluid flow passing through it, and mechanism (88), made with the possibility of bringing the valve element (62) in close Toe position and retaining the valve element (62) in the closed position until a threshold pressure drop across the valve element. The mechanism can work on the principle of magnetism.
